Which statement describes the changes that occur as the oxygen molecule is produced given the equation representing a reaction?
Given the equation representing a reaction:O. + O –> O2 Which statement describes the changes that occur as the oxygen molecule is produced? Energy is released as bonds are formed. Which diatomic molecule is formed when the two atoms share six electrons?
Which change affects both the rate and the activation energy of chemical reaction?
Temperature – Changing the temperature of a chemical reaction also affects the reaction rate. When you heat a substance, its particles move faster. Faster-moving particles have more energy, which helps reactants get over the activation energy barrier more quickly.
What causes a chemical reaction?
Reactions occur when two or more molecules interact and the molecules change. Bonds between atoms are broken and created to form new molecules. That’s it.
What are the products in the equation below CH4 2O2 → CO2 2H2O?
CH4 + 2O2 → CO2 + 2H2O Incomplete combustion – carbon monoxide and water.

What is the balanced equation for the complete combustion of ethene?
The equation for the complete combustion of ethene is (C_2H_4) is C_2H_4(g) + 3 O_2(g) —>…
What conditions must be met in order for a chemical reaction to occur?
Molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. Molecules must collide with the proper orientation. A collision that meets these two criteria, and that results in a chemical reaction, is known as a successful collision or an effective collision.
How the factors affect rates of chemical reaction?
Five factors typically affecting the rates of chemical reactions will be explored in this section: the chemical nature of the reacting substances, the state of subdivision (one large lump versus many small particles) of the reactants, the temperature of the reactants, the concentration of the reactants, and the …
What are 3 conditions that can cause chemical reactions to occur?
Three things must happen for a reaction to occur.
- Molecules must collide.
- Molecules must collide with enough energy to begin to break the old bonds so new bonds can form. ( Remember activation energy)
- Molecules must collide with the correct orientation.
What is chemical reaction and equation?
A chemical reaction is described by a chemical equation, an expression that gives the identities and quantities of the substances involved in a reaction. A chemical equation shows the starting compound(s)—the reactants—on the left and the final compound(s)—the products—on the right, separated by an arrow.
What type of reaction is CH4 O2 → CO2 H2O?
combustion reaction
The reaction is named a combustion reaction. When this reaction takes place, the result is carbon dioxide (CO2), water (H2O), and a great deal of energy. Burning methane releases only carbon dioxide and water.
What happens when CH4 + 2O2 reacts with CO2?
In the reaction CH4 +2O2 = CO2 + 2H2O, if 3 mol of CH4 are reacted with 15 mol of O2, what will be the material remaining after the reaction has gone to completion? Look at the stoichiometry of the equation that represents the reaction…. The reaction is BALANCED with respect to mass and charge.
What is the balanced equation for C2H6 O2 CO2 H2O?
C2H6 + O2 = CO2 + H2O – Chemical Equation Balancer
How many grams of CO2 are formed when methane reacts with CO2?
Then convert Moles of CO2 to grams of CO2 by multiplying by the molar mass of CO2. How many grams of CO2 are formed when 2.5 moles of methane are reacted with excess O2 according to the following chemical equation: CH4 (g) + O2 (g) → CO2 (g) + H2O (g)? According to your equation, one mole of CO2 is made for every mole of methane burned.
Is H2 + O2 = 2H2O a combustion reaction?
This is the decomposition/electrolysis reaction: 2H2O=2H2+O2 and this is the synthesis/combustion/oxidation reaction:2H2+O2=2H2O. Is H2 + O2 = 2H2O a combustion reaction? Yes, obviously. Because hydrogen reacts with oxygen to form water.
